Abstract

This paper presents an asymmetrically operated AC-DC converter. The proposed topology achieves an almost unity power factor, reduces the ripple of the input current, and regulates the output voltage. A bidirectional voltage switch is added to the interleaved current-fed converter on the secondary side of the transformer. The newly added switch helps in achieving an improved power factor and regulates the output voltage of the converter by controlling its duty. Primary switches operate with a fixed duty 50% helps in the reduction of input current ripples. All the switches of the proposed converter are soft switched either at turn on or turn-off. This strategy helped achieve an efficiency of 9 6%. A 1.2kW prototype is developed to verify its operation and performance.
